Convolutional neural networks-based early Parkinson’s disease classification using cycling data from a steerable indoor bicycle

Kim Y, Kim J, Kang S, Lee Y, Moon J, Kim SJ, Kim BJ et al.

Key Finding:

CNN model achieved ~86.1% accuracy in early Parkinson’s disease detection using cycling-derived kinetic and kinematic data from the Ultiracer platform.

29 PD patients and 36 healthy controls. Used two 6-axis force-torque sensors (headset spacer and seat post). Input data: 30 seconds of cycling data (force, moment, speed, lateral movement) plus demographic data.

Biomechanical analysis of patients with mild Parkinson’s disease during indoor cycling training

Kang S, Park JW, Kim Y, Moon J, Lee Y, Lee CN, Kim J, Kim SJ, Kim BJ

Key Finding:

Multivariate logistic model achieved 91.4% accuracy distinguishing PD patients from controls. Cycling speed showed highest discriminatory power (AUC: 0.880), outperforming standard gait velocity measures.

39 PD patients and 42 age-matched healthy controls. Identified distinct biomechanical adaptations: PD patients showed higher handle-saddle coordination (0.47 vs 0.11), lower self-selected speeds (6.49 vs 10.28 km/h).

Feasibility and Safety of an Outdoor-Simulated Interactive Indoor Cycling Device for Cardiac Rehabilitation: A Pilot Validation Study

Kim BR, Kim YM, Lee JT, Park SB, Shin HS, Jung JS, Kim HJ

Key Finding:

No adverse cardiac events were observed. The Ultiracer delivered exercise intensity within the therapeutic range recommended for cardiac rehabilitation in CVD patients.

20 male CVD patients (mean age 56.1). Compared cardiopulmonary responses between treadmill CPET and Ultiracer cycling. Device elicited moderate-to-vigorous intensity exercise.

Enabling Clinical Research

The Ultiracer’s free lateral movement and precise, continuous recording of position, steering and balance make it a practical research instrument for studying balance, coordination and movement patterns.

Neurology

Supporting research into Parkinson’s disease detection and monitoring through cycling biomechanics.

Cardiac Rehabilitation

Validated as a safe and effective exercise modality for cardiovascular disease patients.

Biomechanics

Enabling detailed analysis of balance strategies, force distribution, and movement patterns during cycling.

Research Collaboration

We actively collaborate with leading research institutions. Our platform has been used in studies at Korea University College of Medicine and Korea University Anam Hospital. If you’re interested in using the Ultiracer platform for clinical research, we’d love to hear from you.
